The Web in 2020: wohin sich das Web bewegt

Einmal im Jahr trifft sich das World Wide Web Consortium (W3C) zur Meetingwoche. Christian Liebel von Thinktecture war beim diesjährigen Treffen der Arbeitsgruppen in Japan dabei und hat die neuesten Informationen im Gepäck: Welche Spezifikationen gerade im Gespräch sind – welche neuen Schnittstellen das Web bekommen soll – und was das für Webanwendungen im Jahr 2020 heißen könnte.

14. Motivation - Cooperation with FIDO alliance - W3C Recommendation (official standard) - Alternative, passwordless authentication method - Authentication via internal authenticator (e.g. Touch ID, Win Hello) - Ideally backed by internal hardware module (TPM) - Scoped per origin - Eliminates password theft, phishing and replay attacks - User-friendly The Web in 2020 Wohin sich das Web bewegt WebAuthn

28. Motivation - Communicate updates without distracting the user (in constrast to push notifications) - Typically displays a badge on the home screen, task bar or dock - Appearance varies from platform to platform The Web in 2020 Wohin sich das Web bewegt Badging API
29. API Set the badge navigator.setAppBadge(5); Clear the badge navigator.clearAppBadge(); The Web in 2020 Wohin sich das Web bewegt Badging API
30. Demo • Install (link: http://Airhorner.com) Airhorner.com (Windows / macOS, not Android). • Paste this code in the @ChromeDevTools console: ``` let c = 0; const h = document.querySelector('.horn'); h.addEventListener('click', _ => { navigator.setExperimentalAppBadge(++c); }); ``` • Honk. • T̶h̶a̶n̶k̶ Hate me.

32. Motivation - Devices can go to sleep in order to reduce energy consumption - Different types of sleep: - Turn off the display (screen sleep) - Turn off the CPU (system sleep) - However, this can get bothersome in some situations (e.g. while watching a movie etc.) - The Wake Lock API prevents the device from going to sleep for a given period of time The Web in 2020 Wohin sich das Web bewegt Wake Lock API
33. API let wakeLockObj; if ('getWakeLock' in navigator) { try { wakeLockObj = await navigator.getWakeLock('screen'); console.log('', 'getWakeLock', wakeLockObj); } catch (ex) { console.error('', 'getWakeLock', err); } } The Web in 2020 Wohin sich das Web bewegt Wake Lock API https://developers.google.com/web/updates/2018/12/wakelock

41. The Web in 2020 Wohin sich das Web bewegt WebXR WebAuthn Payment Request API Badging API Wake Lock API Shape Detection API Async Clipboard API Native File System API
42. Motivation - Currently, websites only have very limited access to the file system - Some applications heavily rely on working with files (e.g. Visual Studio Code) - Wouldn’t it be great if your web application could open files or folders from the native file system? The Web in 2020 Wohin sich das Web bewegt Native File System API
43. API (may change!) if ('chooseFileSystemEntries' in window) { const handle = await window.chooseFileSystemEntries(); const file = await handle.getFile(); // do something with the file } else { // use fallback API or disable feature in app } The Web in 2020 Wohin sich das Web bewegt Native File System API

46. The Web in 2020 Wohin sich das Web bewegt Where’s the Web Heading to?
47. - Web is getting more and more capable - The Web is establishing itself as an application platform - But: Web is threatened by alternative approaches and platforms, support for modern Web API varies from platform to platform - You can make a difference! - File bugs in browser engine bugtrackers - File Fugu requests: http://bit.ly/new-fugu-request The Web in 2020 Wohin sich das Web bewegt Where’s the Web Heading to?
